Trouble? Contact listmas...@lists.debian.org If you want blistering performance for ultra gaming, then others may be better BUT I've got an earlier Opteron in an earlier Tyan motherboard available to me - which has been running more or less 24/7 for three years and supporting a community of users for a while. Get good quality memory (possibly ECC memory if you can) and you'll have a workhorse for a long period of time. AndyC - who has built servers using cheap motherboards and skimped on expensive RAID controllers by using Linux software raid :) Software raid is do-able. Cheap motherboards work for a while then can cause problems. If I'd buy again, I'd buy Tyan, good quality dual core Opterons and as much ECC memory as I could fit in. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

See my previous email about the difference between "workstation" and "consumer" class products. There are "fine" products in both classes. You are of the belief that only the "workstation" class products are "fine". You are _wrong_, but apparently rich. So, buy what you want. You won't necessarily get the "best" buying "workstation" class. In fact, most "workstation" class mobos use slow memory standards. They are always a generation behind so they can claim "stability" and charge more for older technology, driving up profits. In essence, making "suckers" of un/under educated buyers. > 1. > For AMD Opteron 1356, look this : > http://www.newegg.com/Product/Product.aspx?nm_mc=AFC-SlickDeals&cm_mmc=AFC-SlickDeals-_-NA-_-NA-_-NA&Item=N82E16819105214 Newegg no longer sells that model. Says so right in the link. > ? Impossible to find the Supermicro MB's. -> ? How so? http://www.supermicro.com/Aplus/motherboard/ Best AMD boards on the planet. From a premier Intel contract manufacturer, nonetheless. Supermicro has been manufacturing desktop and server motherboards for Intel for over 10 years, in addition to their own Supermicro branded Intel chip motherboards. They started manufacturing AMD CPU boards shortly after the Opteron hit the market. You probably won't find them on Newegg. They have an authorized dealer channel. Find a dealer, find a board. ;) > But I have simply a doubt... Is the AMD Opteron a good choice ? > I *presume* it's the best of AMD, and I wonder if Intel would be better. No, the Opteron is a bad choice for a single socket workstation. You pay 10-50% more for the Opteron name regardless of any additional capabilities, the only of which there are being an additional HT link on the 800/8000 series Opterons. Single socket Opty's are identical to their Phenom counterparts, they just cost more due to the "target market". BTW, I've never heard of threaded perl code. Unless you're running multiple perl programs (3 or more) simultaneously you won't benefit from a quad-core CPU. In which case, again, go with the faster dual core CPU instead of the slower quad core. If you _will_ be running more than 3 scripts regularly, then I'd recommend going with this AMD cpu and the previous parts list: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103696 I still think your best bet is to go with the parts list I previously mentioned. And get 4 Western Digital 300GB Raptor SATA2 drives. Fast drives are always better for DB servers: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136322 Use mdadm/LVM and mirror a 100MB /boot and 30GB /root across all four drives.

Celejar has a point here. I just upgraded a Dell Inspiron 8600 laptop running Lenny 5.0.3 from 512 to 1.25 GB RAM and noticed hardly any difference after about a week of usage. Granted, I'm just doing typical non-intensive web browsing, spreadsheets, etc. However, I feel better about it so that's worth something right? :) FWIW, in the past the biggest improvement I've seen is upgrading the laptop hdd (regardless of laptop make or model) from a 5,400 rpm disk to 7,200. Most desktop hdd's these days are 7,200 rpm so my point is useless for desktop discussions. Mark

If you factor in overall price/performance/watt this statement becomes even more true. I wasn't generalizing, I was being quite specific. I think more cores are better, with the understanding that this is something that will be more important in the near future, less important Right Now. What I was being specific about was that the Core i7 with the X58 chipset has the ability to go faster than the stated operating frequency anytime all four cores and eight threads aren't being used. If you are insisting on being loyal to AMD, then it doesn't apply. I would like to reiterate that we don't know OP's application. Assuming Desktop, the choice of CPU isn't critical. Almost any will do. The exception possibly being lots of video encoding or GIMP/'Shop, in which case more threads/cores and memory are important.

For the vast majority of desktop applications, the level of process forking and/or threading isn't sufficiently high enough to allow a lower frequency quad core CPU to give better performance than a higher clocked dual core CPU, assuming the two CPUs are of the same architectural family, in this case AMD. If you factor in overall price/performance/watt this statement becomes even more true. Take the Phenom II X2 vs the Opty 1356 for example. 3.1 GHz vs 2.3 GHz. The L3 cache is the same at 6MB, as is the core microarchitecture (phenom II x2 is a quad core chip with two defective cores disabled mind you), but the two cores of this Phenom run 700MHz faster than the Opty cores. That's a 35% clock speed difference and will definitely be noticeable whilst running the vast majority of desktop apps, such as FireFox, java(script), Flash, Acrobat (other PDF readers), Mplayer, etc. I'm not a big fan of the Slashdot javascript driven web site because it's so darn CPU intensive and doesn't need to be. It's inefficient as hell. The 3.1 Phenom x2 will run considerably faster than the 2.3 quad Opty whilst participating on Slashdot due to the jscript being single threaded. There are many many more examples that prove my point. I almost originally recommended a 3Ghz Athlon II x2 as it's some ~$30 cheaper than the Phenom II x2 above. The Athlon II is a clean sheet dual core design, not a quad core reject with cores disabled. It has a 65W TDP vs 80W TDP, and would give almost identical performance for the vast majority of apps because its two L2 caches are twice the size of the Phenom x2's and have much lower latency than the 6MB L3 on the Phenom. However, Amel is putting 8GB of RAM in the system, and if he actually runs a big app or combo of apps simultaneously that put a good dent in that 8GB of RAM, the 6MB L3 of the Phenom x2 would have a slight advantage here. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Good advice. ;-) I agree, except that, if I understood correctly, he already has the CPU (though I disregarded this in my own post). So he would want a motherboard he can use with his Opteron. The question of dual-core vs. 4-core has been raised; with i7, you get potentially the best of both with "turbo boost". It is capable of shutting down unused coes while speeding up in-use ones to keep power/thermal dissipation within the spec'ed envelope. This works well IME, although I don't know if it has kernel support in Linux or Debian (or whether it requires it.)

I have actualy an AMD Opteron and the idea is, for the moment, to buy : - CPU AMD Opteron 1356 - Motherboard Tyan Tomcat n3400B (S2925-E) - MemoryKingston KVR800D2E6K2/4G (2x kit of 2x2GB = 8GB) Perhaps somebody have an experience with some of that. Your best bet is usually to go with newer + faster. This would seem to suggest Intel, Core i7 or i5. Lynnwood (Core i5, socket LGA 1156) gives a good price/performance. However, you are thinking workstation class motherboard. This would imply possibly two-socket. Intel is definitely more expensive there, if you need a Xeon. So I would look to other considerations, like finding the motherboard with the capabilities you need, or what support it has for the OS you are running or what support the OS you are running has for the motherboard. (Debian, certainly.) Then get the CPU that works in that motherboard. Other considerations besides 64-bit are virtualization support and upgrades. Newer is better, here. If you have the CPU in hand, and are just looking for what to build a system around, look out for flexibility with upgrades and reliability. If you build a new desktop every three years like I do, that may be a different choice that if you are building a machine to last throughout the ages. (Which seems to be a Linux user's tradition. There are people who are still trying to get kernel 2.6.32 to run on a 386sx-16 motherboard with 4 MB from the late 'eighties.) You named specific memory and motherboard. Maybe a few people have experience with one or the other, but I doubt many have used that exact combination. Tyan and Kingston are reputable names. I have gone the consumer/enthusiast-grade route with a Core i7 socket 1366 board, a variant of the ASUS P6T line of boards, and I am happy. It was not the most economical route, however. It has triple-channel memory, and I have 12 GB. This is about 10 GB more than Debian needs, unless you are doing a lot of virtual server stuff. The i7 has four cores, starting at 2.66 GHz, and SMT (Hyperthreading), so it has eight threads at once. I sometimes run the host OS plus five guest OSes all with 2 GB each, and performance is very nice. The Opteron can do this as well, but it suffers with a high thread count. Visit Anandtech web site to read up on this. The Opteron is fine for a Desktop. If you want to play Crysis, get a Core i7, but to just get the job done, AMD is fine. I guess what I am saying is, look to your application. You did not tell us what you were building this machine for.

Is this for a desktop system? If so your choice of motherboard and proc rev is overpriced and will under perform for the money. A higher frequency dual core CPU will give better desktop performance than a lower frequency quad core CPU. The only difference between a "workstation class" board and a "desktop class" board is cost and "guaranteed compatibility" with a select set of after market components. Given the maturity of the parts in the market today, I would not pay extra money for a "workstation" board. If you want to stick with AMD, I recommend the following: AMD Phenom II X2 550 Black Edition Callisto 3.1GHz 2 x 512KB L2 Cache 6MB L3 Cache Socket AM3 80W Dual-Core Processor http://www.newegg.com/Product/Product.aspx?Item=N82E16819103680 ASUS M4A785T-M/CSM http://www.newegg.com/Product/Product.aspx?Item=N82E16813131609 Kingston HyperX 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 http://www.newegg.com/Product/Product.aspx?Item=N82E16820104163 -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

It isn't really in their use of 64 bits that they distinguish themselves. Intel has the performance crown right now, as usual AMD has nicer price points.
